Can anyone suggest a good co2 controller in the 300-400 dollar range. Already have the tank and regulator, decided to go ahead and grab the controller as well.
I have the Sentinal CHHC-4 and paid 560 for it. I think the Cap ones are around 370. You will need a enviroment controller to hook it up to first.
For the money you cannot beat the Sentinal. I have the Cap one also and it has a sniffer, You just need something to plug it into. Does not work by itself.
